在美国国家标准与技术研究所的电子束离子阱装置上，记录了开放N壳层钕（Nd）离子的精确极紫外光谱。标称电子束能量在0.90 keV至2.31 keV的范围内进行测量。测量的光谱，然后与碰撞辐射模型利用原子数据产生的完全相对论原子结构代码模拟的光谱进行比较。因此，59线从Br-样镍-样钕离子被明确确定，其中大部分是新分配在这项研究中。9个已知的线从Ni-，Cu-和Zn类Nd离子的波长与以前的测量结果非常一致。
Accurate extreme ultraviolet spectra of open N-shell neodymium (Nd) ions were recorded at the electron beam ion trap facility of the National Institute of Standards and Technology. The measurements were performed for nominal electron beam energies in the range of 0.90 keV to 2.31 keV. The measured spectra were then compared with the spectra simulated by a collisional-radiative model utilizing atomic data produced with a fully relativistic atomic structure code. Consequently, 59 lines from Br-like to Ni-like Nd ions were unambiguously identified, most of which were newly assigned in this study. The wavelengths of 9 known lines from Ni-, Cu- and Zn-like Nd ions were in excellent agreement with previous measurements.
